FRED IV. VAUGHAN, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE- HALF TO JOHN D. SIBLEY, OF SAME PLACE.

CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 506,891, dated October 17, 1893.

Application filed June 8, 1893. Serial No. 476,985. (No model.)

To all whom it may concern:

Be it known that I, FRED W. VAUGHAN, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Cash-Registers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of cash registers in which series of reading dials representing different values and adapted to be operated either independently or progressively in connection, are employed.

My invention consists in the construction, arrangement and combination of devices, all of which I shall hereinafter fully describe and specifically claim.

The object of my invention is to provide a cash register which while exhibiting to the customer the amount of his purchase, as in ordinary cases, also makes provision for the indication to the operator of a progressive amount or sum total, representing the entire amount of sales for any given time, the arrangement of the parts being such as to enable them to be manipulated easily and readily and at the same time preventing any tampering with the machine, by which its proper function and operation may possibly be perverted.

Referring to the accompanying drawings for a more complete explanation of my invention,-Figure 1 is a rear elevation of my cash register, the protecting plate B being broken away, anda portion of theoperating wheel E of the first series being also broken away. Fig. 2 is a front elevation showing one of the indicating dials D. Fig. 3 is a vertical cross section in the plane of shaft 0. Fig. 4. is a top view of the trigger P and its connected mechanism. Fig. 5 is a detail view showing the figures on the reverse face of dial D, to be read from the back of the machine.

Ais a suitable frame-work having upon its back a protecting plate B. In the upper portion of one end of this frame-work and plate is mounted a shaft 0, upon the outer end of Which is carried an indicating dial D. '.This dial is provided on its outer face and within view of the customer, with figures representing the nine digits and the zero, in annular series, and corresponding characters are placed upon the inner face of the dial, the uppermost one or more of which can be seen over the top of the frame-work from the back 5 5 of the machine, whereby the operator can tell that the proper figure is uppermost. This dial is preferably covered by a casing 61 having an aperture in its uppermost portion, through which one of the characters may be seen.

Upon the inner end of the shaft 0 is rigidly mounted an operating wheel E which has an inwardly projecting flange 6 provided with ratchet teeth 6 on its inner surface. This 65 wheel has around its periphery a series of holes 6 beside each of which is a character denoting its value, namely, the nine digits and the zero, and these characters are in locations corresponding to those of the same characters upon the indicating dial D on the front of the machine. Into these holes is adapted to be removably fitted a handled pin e Loosely mounted upon the shaft 0 is a hub I or sleeve F which carries the reading dial G, said dial having a peripheral flange g separated by an intervening groove g. The reading dial G lies just without the protecting plate B, while its flange 9 lies within said plate, and said dial carries an actuating pawl I, controlled by a spring, and adapted to engage the ratchet teeth e' on the inner surface of the flange e of the operating wheel E.

The reading dial is provided on its face with characters representing the nine digits and the zero, and these are adapted to suecessively appear behind a sight aperture 9 in the operating wheel E. The periphery of the flange of the reading dial G is provided 0 with ratchet teeth g with which a springcontrolled retaining pawl J is adapted to engage. A spring K is mounted upon the shaft 0, preferably between the indicating dial D and the face of the protecting plate B, said spring being adapted to return the shaft 0 as a will be presently explained.

Pivoted to the protecting plate B is a bevelended latch L behind which is a fixed stop M, said latch and stop lying in the path of the zoo handled pin 6 of the operating wheel E.

N is a fixed stop on the face of the frame A, with which a suitable stop cl on the indicating dial D is adapted to come in contact.

The operation of these parts is as follows: Assuming the indicating dial D to be in position to show the zero at its uppermost portion, and that the operating'wheel B shows its zero in a corresponding position, and that the reading dial G shows its zero through the sight aperture e of the operating wheel, a customer makes a purchase to the amount of five cents. The operator thereupon removes the handled pin 6- from the hole 6 in which it was seated, andmoves it down into the hole e which corresponds withthe figure 5 on the operating Wheel E. He now turns said operating wheel to the right until the handled pin arrives at the pivoted latch L; and said pin then passes under the beveled head of said latch, until it gets behind it and is limited by contact with the fixed stop M. I-Ie thereupon leaves it in this position, the pin being held between the fixed stop M and the latch L. This movement of the operating wheelE has, through the shaft 0, turned the indicating dial D, so that its figure 5 is exhibited to the customer through the opening in the casing 61. This movement has also, through the engagement of the ratchet teeth 6 of the wheel with the pawl I of the reading dial G turned said reading dial, with the wheel, through a corresponding are whereby the zero still appears behind the sight aperture a, but the figure 5 on said reading dial is now down in the position previously occupied by the zero of the sight aperture. Now, another customer makes a purchase to the value of four cents. The operator thereupon removes the handled pin e again and this removal freeing the wheel E of the latch L, said wheel under the influence of the spring K on the shaft 0, flies back again to the left until the stop (1 on the indicating dial D comes in contact with the fixed stop N, which thus limits the movement; and in this limit, the operating wheel E again presents its zero at the top, whileits sight aperture 6 has been carried down toits first position, thus exhibiting the previous purchase 5, and the indicating dial D is carried with it to present its zero again at the top. Now the operator places the pin in the hole 6 representing the figure 4, the amount of the second purchase, and he thereupon turns the wheel E again to the right, until the pin is caught again between the latch L and the stop M. This movement has carried the figure t of the indicating dial D into sight, and has also, through the pawl and ratchet connection, carried the reading dial G around four places, thus presenting the figure 9 on said reading dial in the position previously occupied by the figure 5, and this figure 9 representing the sum of the two purchases is adapted to be exposed through the sight aperture e of the operating wheel, when said wheel is relieved upon a third purchase and flies back to its initial position of zero. Thus the reading dial G is adapted to present a progressive sum,

while the indicating dial D on the front of the machine presents each time the amount of the particular purchase to the individual. It will be observed that as the pawl and ratchet connections effecting these several movements are located behind the protecting plate B, they cannot be tampered with, being protected by said plate and by the inwardly extending flange e of the operating wheel which passes through said plate in an opening just sufficient to receive it.

The parts thus described constitute only the units or cents. To provide for the tens or dimes, I have a precisely similar set of parts as those heretofore described, and which need not be described in detail, their exterior representation being suflicient to understand their presence. These last mentioned parts representing the dimes are adapted to be operated either independently, as those heretofore described, or progressively by the connections which I shall now explain. Upon the flange g of the reading dial G is mounted rigidly a lug O which is adapted to come in contact with a pivoted trigger P, spring-controlled, and carried by a spring-controlled swinging lever Q, to the upper end of which is connected a pawl R, the end of which engages the ratchet teeth 9 of the flange g of the reading dial of the dimes mechanism. This engagement, to prevent slipping, is preferably a forked one, the arms of the pawl passing down on each side of the flange g, thereby avoiding any tendency of the pawl to slip from its engagement with the teeth of said flange. Now, when the reading dial G of the first set is completing its revolution, its lug 0 coming in contact with the pivoted trigger P, will carry said trigger forwardly with it, and as the trigger moves forwardly, the lever Q is carried over and the pawl R will move the dimes mechanism one notch. The trigger at its inner end bears upon an inclined cam S, which gradually throws said trigger over, as it moves forward, and when the required movement has been reached, this throwing over of the trigger releases its other end from the lug Oof the reading dial G, thus relieving said dial, and allowing the springcontrolled lever Q with its pawl R to return to its normal position, for engagement of the latter with the next tooth of the reading dial of the dimes mechanism. Similarly a bun dreds or dollars set is to be used, operated by the same or similar mechanism from the tens or dimes set. Thus as a final result and at the end of a stated period, as, for example, at the end of the day, the total sum of the pur chases for that period may be read through the sight apertures of the operating wheels E, this reading being backward in order that the several indicating disks D on the front of the machine may be arranged to show from left to right.

The dimes mechanism is operated alone when an amount of a ten value is received,

and similarly the dollars mechanism when dollars are received.
